Measuring and analysing SEO performance through web design

Here is something many business owners avoid: you can have a great-looking website, strong writing and a designer who says it is SEO friendly. But if you don’t track what happens after it goes live, you are just guessing. Guessing costs money.

The good news is that measuring SEO performance is not as hard as it sounds. You only need a few free tools, a couple of hours to set them up and a clear idea of which numbers matter. We will show you how to set everything up, which numbers to watch and what to do when something is not working.

The tools you need (and they are all free)

You do not need to spend hundreds of pounds on fancy software. Four free tools cover most of what a small or medium business needs.

Google Search Console

This is the main one. It shows which search terms people use to find your site, how often your pages appear in Google, how many people click, and which pages are indexed. If you only set up one tool, choose this. It takes about ten minutes.

Google Analytics 4 (GA4)

This shows what people do after they land on your site. You can see where they go, how long they stay, what they click, and if they contact you. It is not the easiest tool to use, but it is free and very useful.

Bing Webmaster Tools

Bing is smaller than Google, but it still matters. It also powers some search tools and voice assistants. Setup takes about five minutes and gives you extra data that many people miss.

PageSpeed Insights

You do not install this one. You just paste in your website link and it checks how fast your site loads. It also shows what is slowing it down. Speed affects your rankings, so this is worth checking often.

Set up these four before you do anything else. Without them, you are working without clear data.

When it is worth paying for tools

The four free tools above will take most small and medium businesses a long way. But at some point you hit their limits. You can’t see what competitors rank for, it is harder to find backlink opportunities and you can’t track rankings by location or postcode. That’s when paid tools start to be useful. You don’t need loads of them. One all-in-one tool, plus another if local search matters to you, is usually enough.

Semrush

A popular all-in-one SEO tool. It’s strong for competitor research. You can see which keywords your rivals rank for, where their traffic comes from, and which pages bring them the most visits. It also does keyword research, site audits, and rank tracking. If you only want one tool for SEO, this is usually it.

Ahrefs

Best known for backlinks. People mainly pay for its huge link database. You can track your own backlinks, spot bad ones, and see who links to your competitors so you can target the same sites. It also has keyword and content tools, but backlinks are the main reason people use it.

Ubersuggest

A cheaper tool from Neil Patel. It covers the basics like keyword ideas, search volume, simple competitor data, and site audits. It is not as deep as Semrush or Ahrefs, but it is a good starting point if you want more than free tools without a big monthly cost.

BrightLocal

Made for local SEO. Useful for businesses that serve a specific area, like a London plumber or a chain of clinics. It tracks rankings by postcode, checks your Google Business Profile, monitors local listings, and helps with reviews. Bigger SEO tools don’t handle this well. If “near me” searches matter to you, this fills the gap.

The metrics that actually matter

Most SEO reports include numbers that look impressive but do not tell you much. Here are the ones that actually matter.

Organic traffic

This is the number of people who find your site through search engines, not ads or social media. You can see it in GA4 under Acquisition. It is the simplest sign of whether your SEO is working. If organic traffic is going up month by month, things are moving in the right direction. If it is flat or falling, something needs attention.

Impressions and clicks in Search Console

Impressions show how often your site appears in Google results and clicks show how often people actually click on it. Both matter, but they tell you different things. If you have lots of impressions but few clicks, your titles and descriptions are not doing their job. People see your page and choose someone else.

Average position

Search Console shows the average position of your pages for each search term. Position 1 is the top of page one. Position 10 is the bottom of page one. Position 50 is usually buried on page five, which most people never see. Watch this number over time. If a page moves from position 40 to position 15, that is progress even if traffic has not changed yet. It means Google is starting to rank it higher.

Click-through rate (CTR)

This is the number of clicks divided by the number of times your page shows in Google. If your page is in position three, you should expect around 10% of people to click it. If you only get 2%, something is wrong with how your result looks in Google. Most of the time it is the title or the description. It is not clear enough or not interesting enough, so people skip it.

Bounce rate and engagement time

Bounce rate is the percentage of visitors who leave after seeing one page. Engagement time is how long they stay on your site. If people arrive and leave in under ten seconds, they did not find what they were looking for. That can be caused by slow loading, poor design, or content that does not match what they searched for.

Core Web Vitals

These are Google’s checks for how fast and stable your site feels. There are three parts. How fast the page loads. How quickly you can actually use it, like clicking buttons or scrolling. And whether the page stays in place while it loads. That last one means things on the page should not suddenly move after they appear. For example, you try to click something, then an image or banner loads and pushes everything down, so you click the wrong thing.

You can see these scores in PageSpeed Insights or in the Core Web Vitals report in Search Console. If any of them are marked as poor (red), your site may rank lower in Google.

Metrics to mostly ignore

Some numbers look important but are not.

Domain authority

This is a score made up by SEO tools like Moz and Ahrefs. Google does not use it. It can be a rough guide to how strong your backlink profile is, but do not obsess over it.

Total keywords ranking

You might see that your site ranks for 400 keywords. Sounds good. But if 380 of them are in position 90 on page nine of Google, none of them bring any traffic. Quality of rankings matters, not quantity.

Page views

Big number, often meaningless. One visitor clicking five times gives you five page views but it is still one visitor. Look at users and sessions instead.

What to do with the data

Setting up the tools is step one. Looking at the data is step two. Acting on it is where most people stop. But that is the part that actually makes a difference. Here is a simple monthly routine.

Open Search Console

Go to the Performance report. Which search terms brought the most clicks this month? Which pages got the most impressions? Sort by CTR and find pages that get lots of impressions but a low click rate. These are pages where a better title and description can bring you more traffic without changing your ranking.

Find your almost-ranking pages

In Search Console, filter by pages in positions 8 to 20. These are pages sitting on page one or two of Google. A bit of work (adding more content, improving internal links, updating the page) often pushes them up to positions 1 to 5, which is where most of the clicks are.

Check GA4 for pages that get traffic but no conversions

If a page brings in 500 visitors a month but nobody contacts you from it, something is broken. Maybe there is no call to action. Maybe the contact form is buried. Maybe the page ranks for the wrong search term. Fix it.

Run PageSpeed Insights on your most-visited pages

If any of them are loading slowly on mobile, that is the first thing to fix. Speed affects rankings and conversions at the same time.

Compare month to month

Compare last month’s numbers with this month’s. Is organic traffic up or down? Which pages changed the most? Why? The point is not to hit a target, it is to notice what is moving.

A few tips from our own web design team

After building hundreds of websites, a few patterns come up again and again. First, set up a simple dashboard. Do not switch between different tools every week. Looker Studio (free from Google) brings data from Search Console and Analytics into one place. Set it up once, then check it for a couple of minutes each week.

Second, pick three numbers and track only those for the first six months. For most of our web design clients, that is organic traffic, conversions from organic traffic and average position for their top five keywords. Everything else is noise until those three are moving in the right direction.

Third, screenshot your numbers every month. Tools change, dashboards break, accounts get lost. A folder of monthly screenshots is the simplest backup you can have.

Final thoughts about measuring and analysing SEO performance through web design

SEO without tracking is a waste of time and money. You do not know what is working, you cannot show results and when something breaks you do not know why.Set up your tools during the build, check your numbers every month and act on what you see.
